Use of Non-GAAP Financial Measures Hologic, Inc. (the “Company”) has presented the following non-GAAP financial measures in this presentation : adjusted net income and adjusted EBITDA of each of Hologic and Gen-Probe, and pro forma adjusted net income, adjusted EPS and adjusted EBITDA of the combined company.  The Company defines its non-GAAP adjusted net income and adjusted EPS to exclude the non-cash amortization of intangible assets, other acquisition-related charges, such changes for contingent consideration, transaction costs and charges associated with the write-up of acquired inventory to fair value, non-cash interest expense related to amortization of the debt discount for convertible debt securities, divestiture and restructuring charges, non-cash loss on exchange of convertible notes, and one-time, nonrecurring, unusual or unanticipated charges, expenses or gains. The Company’s non-GAAP adjusted EBITDA excludes from its GAAP net income: (i) the items excluded in its calculation of non-GAAP adjusted net income; (ii) interest expense, net, not otherwise excluded in calculating its non-GAAP adjusted net income; (iii) provision for income taxes; and (iv) depreciation expense. The reconciliations of these historical non-GAAP measures to each of Hologic’s and Gen-Probe’s GAAP financial measures for the periods presented, are set forth on slide 22. Future GAAP EPS may be affected by changes in ongoing assumptions and judgments relating to the combined company’s businesses, and may also be affected by nonrecurring, unusual or unanticipated charges, expenses or gains, all of which are excluded in the calculation of non-GAAP adjusted net income, adjusted EPS and adjusted EBITDA as described in this presentation. It is therefore not practicable to reconcile this non-GAAP guidance to the most comparable GAAP measure. The Company believes the use of these non-GAAP metrics are useful to investors in comparing the results of operations for comparable periods by eliminating certain of the more significant effects of its acquisitions and related activities, non-cash charges resulting from changes in GAAP, and litigation settlement, divestiture and restructuring. These measures also reflect how the Company manages the business internally. In addition to the adjustments included in the calculation of the Company’s non-GAAP adjusted EBITDA eliminates the effects of financing, income taxes and the accounting effects of capital spending. As with the items eliminated in its calculation of non-GAAP adjusted net income, these items may vary for different companies for reasons unrelated to the overall operating performance of a company’s business. When analyzing the Hologic’s, Gen-Probe’s and the pro forma combined company’s operating performance, investors should not consider these non-GAAP financial measures as a substitute for net income prepared in accordance with GAAP. . 3
